Naval Surface Warfare Center, Crane Division (NSWC Crane), has designed, patented, and developed a detection system for identifying a signal of interest in an environment saturated with different signals. The suite of patents in the "Identification of Target Signals in Radio Frequency Pulsed Environments" technology includes both the system and method of detection. The system includes a test set that detects phase-shift keying (PSK) modulation and measures radio frequency (RF) amplitude. PSK is a digital modulation scheme that conveys data by modulating the phase of a carrier signals. Wireless LAN, RFID, and satellite communications are some of the technologies and industry areas that utilize PSK modulation.
